Using smart bombs is a very expensive way to NOT to achievement military victory by which I mean the enemy cries uncle and dances to the victor's tune. Why should the enemy give in when the population which supports it politically, economically and morally is immune from attack? Lincoln, FDR and Truman knew that enabling the Forces of Good to triumph in the Civil War and WWII. Wilson didn't so the Forces of Darkness prevailed bringing the Nazis, Soviets and radical Islamic terrorism.
